No. 598,692! Int. Cl.E04c 2/10, 2/46; E0411 2/72 U.S. Cl. 52-309 (Ilaims ABSTRACT OF THEDISCLOSURE This application relates to a siding construction especiallyadapted for homes, factories and similar building structures, and theprimary object of the invention is to provide a siding constructionconsisting of a plurality of interlocked slabs or panels, and moreparsicularly, to a specialized nailing construction.

Rigid vinyl and similar thermoplastic materials or even aluminum have ahigh coefficient of thermal expansion, relative to conventional buildingmaterials, such as wood, steel and the like. For example, in warmclimates during the summer months, sidings can easily reach an extremetemperature of 120 F., and it is not at all uncommon for siding to beinstalled during a winter at temperatures of 20 F. or even below. Wheresuch extreme temperatures are involved, a temperature differential of atleast 100 can very definitely occur, and in the case of a foot vinylsiding, a thermal expansion and contraction of at least one-half inchwould occur.

The most convenient way to install siding panels is simply to nail themonto the wooden surface, or in some instances onto studs themselves,using large headed roofing nails. It has also been conventional toaccommodate normal movement of the panel to drive the fastening meanssuch as nails through the center of a slot instead of merely through ahole of limited dimensions. This method is feasible only if the nail isnot driven in so hard by the workman that excessive pressure between thenail head and the siding prohibits movement and, very difficult removalof the fastening means should it be desired to replace the panels at afuture date.

A primary object of the invention is therefore accordingly to providesiding panels, either lined or unlined with insulating board, with meansspecifically designed to prevent the fastening means being driven toohard into the wooden background or supporting means.

Referring to the drawings, it will be observed, purely for purposes ofillustration, I have disclosed one embodiment of my invention, whereinFIGURE 1 illustrates a panel construction, such as a vinyl panelconstruction, in detailed enlargement. FIGURE 2 shows an elongatedcross-section of a typical siding panel formed in accordanee with theinvention. FIGURE 3 illustrates the interlocking arrangement of a seriesof panels which, in this instance, are provided with a lining ofinsulating material such as asbestor or the like. FIGURE 4 shows,illustratively, the installation of elongated panels to a buildingsiding in accordance with the features of the invention. FIG- URE 5illustrates the usual type of panel construction employed in sidings.

In accordance with the invention, I have found that the provision of abulged or semi-spherical domed arrangement, 10, which can be arrangednear one end of the panel, although it should be distinctly understoodthat it could be located virtually at any location in the panel facing.

This bulged area, 10, is provided with a slot, 11, to which a fasteningdevice or nail can be driven in the manner illustrated in FIGURE 3 ofthe drawings. FIG- URE 2 shows in a cross-section the arrangement of abulged nail area formed in accordance with the invention adjacent theend of a building panel, 12, and near an interlocking hood portion, 14.

It will be understood, as pointed out above, that the invention would belikewise applicable where the fastening or nailing means are locatednear the middle of the panel instead of being adjacent the end. However,particularly in view of the mounting arrangement shown in FIGURE 3, itis more convenient and attractive to locate the fastening means adjacentthe end, for example, the upper end of the siding panel as clearlyillustrated and shown in the drawings. By these means, it is possible tointerlock adjacent panels, 16 and 17, with the panel 12, at oppositeends thereby concealing the bulged portion, 10, and the driven in nailwith this panel, 12. This interlock is firmly made so that there is nopossibility of the panels becoming displaced relative to one another.FIGURE 4 illustrates typically a building construction formed frominterlocking elongated panels, 19 and 20.

The primary and obvious advantages of the arrangement which I havedescribed herein involve the principle that a plane becomes tangent tothe circle at one point only, and therefore there is minimum contactbetween the nail head and the siding itself. Also, should a nail bedriven too hard, the domed portion, 14, will distort slightly giving theworkman visual evidence that the nail has been driven in slightly toofar. As clearly shown in the drawings, particularly FIGURE 3, there isconvenient room to pull the nail out slightly with a claw hammer orsimilar device which encourages the workman or op erator to correct andrectify any over-driven nails.

Also, the domed semi-spherical nail portion is considerably stiffer ormore unyielding than a fiat section and therefore the panels are muchmore easily slidable on thermal change instead of bulging or bucklingbetween the driven nails.

Although I have shown in FIGURE 2 a considerable number of nailopenings, it is understood that any number of nail openings may beemployed What is claimed is:

1. A siding panel comprising in combination a generally rectangularperipheral configuration sheet panel having an elongated protuberancesemi-circular in cross section integrally extending directly upwardlyfrom a first longitudinal edge thereof, the convex surface of saidprotuberance being disposed in the same direction as the front surfaceof said sheet panel, said protuberance having a plurality of spacedfastener apertures disposed near the apex thereof, a first interlockingflap integrally extending from the connection of said protuberance andsheet panel in a downward projection in spacial overlapping relationshipwith a portion of the front surface of said sheet panel, and a buttflange having a second interlocking flap integrally extending in anupward direction therefrom integrally disposed in a rearward directionfrom a second longitudinal edge of said siding panel.

2. The siding panel of claim 1 wherein said spaced fastener aperturesare horizontally elongated in configuration.

3. The siding panel of claim 1 fabricated from polyvinyl chloride.

4. The siding panel of claim 1 wherein said first and gecczlndinterlocking flaps terminate with inturned lock ea s.

5. A plurality of the siding panels of claim 4 mounted in courses on asubstrate with fastening means transversing 3 said apertures and withsaid first and second interlocking flaps, respectively, of verticallyadjacent siding panels in engagement.
